Description

Technical Field

[0001] The utility model relates to the technical field of blasting, in particular to a charging structure for reducing the bulk rate of anisotropic inhomogeneous rock masses. Background Art

[0002] The charging structure of low anisotropic heterogeneous rock mass with large block rate usually involves reducing the large block phenomenon after rock crushing by optimizing the layout of explosives. Due to the differences in its lithology, structure and physical and mechanical properties, anisotropic heterogeneous rock mass often leads to uneven rock fragmentation after blasting, resulting in larger rock blocks. Therefore, designing a suitable charging structure can improve the blasting effect. Common practices include adjusting the density distribution of the charge column, the type of explosives and the spacing between charging holes, using segmented charging technology or adjusting the blasting sequence, aiming to reduce the formation of large blocks by enhancing the crushing of local areas.

[0003] According to a publicly disclosed charging structure (Announcement No.: CN209877796U), it includes an explosive, a charging hole, a detonating device and a sealant. The charging hole is set on the explosive, and the detonating device includes a detonator, a detonator leg wire and explosives. One end of the detonator leg wire is connected to the detonator, and the other end of the detonator leg wire extends to the outside of the charging hole. The detonator is set inside the charging hole, the explosive is set inside the charging hole, the detonator is wrapped with the explosive, and the sealant is set at the opening of the charging hole, and the sealant seals the opening of the charging hole.

[0004] However, in the above design, after blasting, there are still large stones that are not conducive to the work, and needs to be improved. Utility Model Content

[0007] The side surface of the sliding block is fixedly connected with a pressure plate, and the top of the connecting plate is fixedly connected with a handle. The design of the handle is conducive to facilitating the rotation of the hollow threaded rod by the staff.

[0008] The limiting block contacts the limiting plate, and the side section of the limiting block is set to be triangular. The design of the limiting block is conducive to limiting the connection disk.

[0009] The sliding block is slidably connected to the top of the inner wall of the hollow block. The side cross-section of the hollow block is set to be concave. The design of the sliding block is conducive to driving the limit block to move.

[0010] A support mechanism is provided on the side of the handle, and the support mechanism includes a vacuum block. The inner side wall of the vacuum block is fixedly connected to a fixed shaft, and the circumferential surface of the fixed shaft is fixedly connected to a support bar. The design of the support bar is conducive to maintaining the stability of the drill bit during vibration drilling.

[0011] The bottom of the support bar is fixedly connected to a return spring, and one end of the return spring away from the support bar is fixedly connected to a hollow bar. The above design is conducive to further enhancing stability.

[0012] The support bar is slidably connected to the inner wall of the hollow bar, and the initial state of the reset spring is set to a relaxed state. The design of the reset spring is conducive to contraction according to the depth of the drill bit entering the soil.

[0013] The side cross-section of the vacuum block is set to be concave, and the side cross-section of the handle is set to be convex. The above design is conducive to enhancing the stability of the machine during operation.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] 1. The utility model drives the threaded barrel, hollow threaded rod, connecting disc, handle, hollow block, connecting spring, sliding block, pressure plate, limit block and other components to cooperate with each other through the rotational force of the connecting disc, thereby realizing the rotation of the handle fixed on the top of the connecting disc, thereby driving the hollow threaded rod threadedly connected to the inner wall of the threaded barrel to rotate, and adjusting the depth of the hollow threaded rod. When the adjustment is completed, the staff presses the pressure plate fixed on the side of the sliding block. During the charging process, different depths of blasting can be carried out according to the size of the stone, thereby reducing the probability of the existence of large stones.

[0016] 2. The utility model drives the vacuum block, fixed shaft, hollow bar, reset spring and other components to cooperate with each other through the sliding force of the support bar, so that during the drilling process, the hollow bar fixed at the other end of the reset spring contacts the ground, and as the drill bit continues to move downward, the gun barrel is driven downward, and the handle is driven downward at the same time. When the handle moves downward, it drives the vacuum block to move downward, thereby driving the fixed shaft fixed on the inner wall to move downward, thereby enhancing the stability of the drill bit during vibration drilling.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1 to 5 As shown, this embodiment proposes a charging structure for reducing the large block rate of anisotropic inhomogeneous rock mass, including a gun barrel 1, a drill bit 2 is fixedly connected to the bottom of the gun barrel 1, a connecting assembly 3 is provided on the circumferential surface of the gun barrel 1, a detonating assembly 6 is provided on the circumferential surface of the gun barrel 1, a charging mechanism 4 is provided inside the gun barrel 1, and the charging mechanism 4 includes a threaded barrel 41, the threaded barrel 41 is fixedly connected to the inner wall of the gun barrel 1, a hollow threaded rod 42 is threadedly connected to the inner wall of the threaded barrel 41, a connecting disk 43 is provided on the top of the hollow threaded rod 42, a hollow block 45 is fixedly connected to the circumferential surface of the connecting disk 43, a connecting spring 46 is fixedly connected to the inner side wall of the hollow block 45, a sliding block 47 is fixedly connected to the end of the connecting spring 46 away from the hollow block 45, a limiting block 49 is fixedly connected to the bottom of the sliding block 47, and a limiting plate 410 is fixedly connected to the circumferential surface of the hollow threaded rod 42.

[0028] A pressure plate 48 is fixedly connected to the side of the sliding block 47 , and a handle 44 is fixedly connected to the top of the connecting plate 43 . The design of the handle 44 is conducive to facilitating the rotation of the hollow threaded rod 42 by the staff.

[0029] The limiting block 49 contacts the limiting plate 410 . The side cross-section of the limiting block 49 is set to be triangular. The design of the limiting block 49 is conducive to limiting the connection disk 43 .

[0030] The sliding block 47 is slidably connected to the top of the inner wall of the hollow block 45. The side section of the hollow block 45 is set to be concave. The design of the sliding block 47 is conducive to driving the limit block 49 to move.

[0031] In this embodiment, when blasting is first required, the staff connects the vibration machine through the connecting component 3 set on the circumferential surface of the gun barrel 1, and then starts the vibration machine to make the drill bit 2 fixed on the bottom of the gun barrel 1 perform drilling work. When the hole is drilled to a certain depth, the vibration machine is disassembled. At this time, the staff rotates the handle 44 fixed on the top of the connecting disk 43, thereby driving the hollow threaded rod 42 threadedly connected to the inner wall of the threaded cylinder 41 to rotate, and adjusts the depth of the hollow threaded rod 42. When the adjustment is completed, the staff presses the pressure plate 48 fixed on the side of the sliding block 47, thereby driving the sliding block 47 to slide. The sliding of the sliding block 47 drives the limit block 49 fixed at the bottom to move and no longer contact the bottom of the limit plate 410. At the same time, the staff pulls the connecting disk 43 so that the connecting disk 43 no longer contacts the hollow threaded rod 42. At this time, the staff loads explosives and buries the detonator, and remotely controls the detonating component 6 set on the circumferential surface of the gun barrel 1 to perform blasting.

[0032] Example 2

[0033] like Figures 1 to 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a second embodiment, a support mechanism 5 is provided on the side of the handle 44, and the support mechanism 5 includes a vacuum block 51, and the inner side wall of the vacuum block 51 is fixedly connected with a fixed shaft 52, and the circumferential surface of the fixed shaft 52 is fixedly connected with a support bar 53. The design of the support bar 53 is conducive to maintaining the stability of the drill bit 2 during the vibration drilling process.

[0034] A return spring 55 is fixedly connected to the bottom of the support bar 53 , and one end of the return spring 55 away from the support bar 53 is fixedly connected to a hollow bar 54 . The above design is conducive to further enhancing stability.

[0035] The support bar 53 is slidably connected to the inner wall of the hollow bar 54. The initial state of the return spring 55 is set to a relaxed state. The design of the return spring 55 is conducive to contraction according to the depth of the drill bit 2 entering the soil.

[0036] The side cross-section of the vacuum block 51 is set to be concave, and the side cross-section of the handle 44 is set to be convex. The above design is conducive to enhancing the stability of the machine during operation.

[0037] In this embodiment, when the drilling process is finally carried out, the hollow bar 54 fixed on the other end of the return spring 55 contacts the ground. As the drill bit 2 continues to move downward, the barrel 1 is driven to move downward, and the handle 44 is driven to move downward at the same time. When the handle 44 moves downward, it drives the vacuum block 51 to move downward, thereby driving the fixed shaft 52 fixed on the inner wall to move downward, and at the same time drives the support bar 53 fixed on the circumferential surface to move downward and slide downward on the inner wall of the hollow bar 54. When the support bar 53 slides downward, the return spring 55 fixed on the bottom is in a taut state. When the drilling is completed, the staff removes the connecting plate 43 so that the connecting plate 43 no longer contacts the hollow threaded rod 42, which is convenient for the staff to use it again.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
